CAN-CRIMPING MACHINE.

Specification of Letters Patent.

PatentedFeh29J916.

To all whom it may concern:

Be it known that I, LoUIs N. TRUDEAU, a citizen of the United States, residing in Detroit, county of Wayne, and State of Michigan, have invented a new and useful Improvement in (Ian-Crimping Machines, of which the following is a specification.

This invention relates to improvements in can crimping machines.

One object of the invention is to provide a crimping machine adapted for securing covers to non-circular cans in which one of the chucks for clamping the cans has provided therewith an integral guiding cam for tion, parts illustrated in Fig the crimping roller, which cam corresponds in cross sectional shape-to that of'the can being operated upon.

Other objects of the invention are to provide a crimping machine of simple construcof which may be readily interchanged to adapt the machine for operating on cans of different shape; to provide a crimping machine in which all the parts are thrown into operative position by a single means and in such order that the can is first clamped between the chucks, the power clutch and crimping roll being thrown into operation subsequent to the chucking.

The invention furthermore consists in the improvements in the parts and devices and in the novel combination of the parts and devices as herein shown, described or claimed.

In the drawing forming a part of this specification, Figure 1 is a side elevation of a machine embodying my improvements. Fig. 2 is a front elevation of the machine 1. Fig. 3 is an enlarged detail sectional view taken substantially on the line 3-3 of Fig. 1. Fig. 4 is a broken sectional view taken substantially on the line 44 ofFig. 1. Fig. 5 is a vertical detail sectional view taken substantially on the line 5-5 of Fig. 2; and Fig. 6 is a vertical sectional view taken substantially on the line'66 of Fig. 5.

As shown in the drawing, the machine comprises a base or standard 10 from which extends an upright or supporting post 11,

the latter having mounted therein in suitable bearings,a shaft 12 driven from any suitable source of outside power (not shown) through pulley 13 and clutch 14. The shaft 12 at one end thereof is providedwitll a bevel gear 15 meshing with a similar bevel gear 16 secured to a vertical chuck spindle 17, on the lower end of which is detachably mounted a combined chuck and cam A, described more in detail hereinafter. In

alinement with the spindle 17 and below the latter is a vertically reciprocating lower chuck spindle 18 mounted in a suitable bearing 19 and having rotatably mounted therein a lower chuck or clamp plate 20. lhe spindlev18 is given reciprocating movement by means of an oscillatable lever 21 pivoted to a stationary part of the base 10, the lever 21 having pivotally secured thereto at its front end a collar 22 slidable on the spindle 18 and between which and another adjustable collar 23 on said spindle is placed a spring 24, thereby providing a yieldable connectionbetween the lever 21 and lower chuck 20 to adapt the machine for operating on cams varying slightly in length. The lower chuck 20 is normally held in its lowermost position by a spring 25 secured to the frame and to the rear end of the lever 21. The clutch 14 and the lever 21 are operated by a foot treadle 26 pivoted-to the standard pivotally connected therewith a link 28 also pivotally connected to the lever 21 andto a connecting rod 29, the latter and the link 28 having a pin and slot connection 30 versely extending recess 36 in the upright 11 is a box 37 the latter comprising a lower member 38 and a top plate 39 bolted thereto. The lower member 38 of the box 37 has a depending'projection 40 threaded to receive an adjusting screw 41 adapted to be 10 at 27, the treadle having,

- therebetween to provide a certain amount of operated by a turn nut 42, by which means I the box 37 can be adjusted laterally of the machine. Within the box 37 is slidably mounted a slide 43 which carries a cam guide-roll 44 at its outer end. The slide 43 is yieldingly pressed outwardly by two springs 45 seated in suitable pockets in the slide, said springs at their inner ends engaging a depending plate 46 secured to the box 37. Also slidably mounted within the box 37 and independently of the slide 43 is a crimping roll-carrying slide 47 which carries at its outer end a crimping roll 48 adapted to turn or crimp the flange of a can top 49 to secure it to a can body 50. Pivotally connected to the inner end of the crimping roll-carrying slide 47 are links 51 forming a toggle with similar links 52, the latterbeing pivotally connected toa pivot 53 adjustably mounted in a slot 54 in an ex tension of the slide 43, the adjustment for the pivot pin 53 being accomplished by means of bolt and nuts 55. A pivot pin 56 conmeets the inner ends of the links 51 and 52 together and also to the link 31, the latter being slidable within a tapered recess 57 in the extension of the slide 43, see .Figs. 3 and 5.

The combined chuck and cam A comprises a lower plate 58 corresponding in shape to and adapted to fit within the usual countersunk portion of the can top and a surface cam 59 formed integral with the plate 58. The combined chuck and cam is detachabl secured to the lower end of the spindle 17 by a screw and nut connection indicated in dotted lines in Fig. 5, thereby adapting the chuck to be removed and replaced by another of different shape or size or both, it being understood that the cross sectional shape of'the chuck and cam will correspond to the cross sectional shape of the can being operated upon.

Itsometimes happens that the cans being operated upon are not uniform in length on all sides and to accommodate for suchirregularities in the cans 1 mount on the chuck 20 what 1 term a universal movable supplemental chuck plate 61, the same having a socket 62 on its under side adapted to fit a ball 63 mounted on the chuck 20. With this construction it will be apparent that the plate 61 can accommodate itself automatically to any irregularities in the lengths of the sides of the cans.

The operation is as follows: The operator movement of the treadle 26 will in turn pull the connecting rod 29, thereby causing the clutch 14 to be thrown into operation and also to project the crimping roll 48 into operative position, this latter result being effected by the straightening out of the toggle composed 'of the links 51 and 52. With the parts in this position, the can will be rotated and the slides 43 and 47 will be guided inwardly and outwardly and in accordance with the contour of the can'by the surface cam 59, it being apparent that when the toggle controlling the slide 47 is straightened out, the slide 47 will move in unison with the slide 43. Both slides will, of course, be always normally urged outwardly into operative position by the springs 45.

The adjusting screw 41 adapts the machine A embodiment of myimprovement, yet it will be understood that various changes and modifications may be made without departing from the spirit of the invention. and all such changes and modifications are contemplated as come within the scope of the claims appended hereto.
